Phase-based Bidirectional Stereo in Coping with Discontinuity and Occlusion

Multiresolution Phase-Based Bidirectional Stereo Matching with Provision for Discontinuity and Occlusion

Stereo Matching With Color-Weighted Correlation, Hierarchical Belief Propagation And Occlusion Handling

In this paper, we contrive a stereo matching algorithm with careful handling of disparity, discontinuity and occlusion. This algorithm works a worldwide matching stereo model which is based on minimization of energy. The global energy comprises two terms, firstly the data term and secondly the smoothness term. The data term is approximated by a color-weighted correlation, then refined in obstru...

Département d ’ Informatique et de recherche opérationnelle ( DIRO ) Rapport technique 1273 Février 2006 Geo - consistency for Multi - Camera Stereo by Marc - Antoine Drouin

This paper introduces the concept of geo-consistency to overcome the occlusion problems associated with wide-baseline multiple-camera stereo. By expressing more formally the geometric relationship between occlusion and visibility, it provides a new tool to understand and compare the behavior of stereo algorithms. In this context, we present a new visibility mask handling that can render most re...

A New Single-phase Symmetrical Cascade Multilevel Inverter with Low Number of Power Switches

In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

Robust Phase Correlation based Motion Estimation and Its Applications

This paper presents a robust phase correlation technique and a compound phase correlation method for reliable sub-pixel image feature matching and motion estimation. A phase fringe filter and a highly robust estimator QMDPE are used to improve the fitting accuracy of the phase difference plane in Fourier domain. A compound phase correlation method is proposed to identify and decompose the multi...
